Description

I have been testing the CustomNPCs mod for Fabric, and it works perfectly in both single-player and regular multiplayer modes. However, when I try to use banners, an error occurs that prevents me from editing or saving the NPCs. I reached out to the developer, and they mentioned that the issue might be related to the hybrid mode. Could you please provide a solution regarding this?

Step to reproduce

Step 1: Install CustomNPCs with banners.
Step 2: Create an NPC with the wand.
Step 3: Close the window, and you won't be able to edit it.
Step 4: Use the soulstone or mob cloner to try to save the NPC
